PORTFOLIO SIDE PROJECTS
Dental Implant Selection Mobile App (Freelance Project) - LINK
Developed a mobile application for a client to simplify the process of selecting dental implants and prosthetic components. The app features a guided questionnaire that helps dental professionals choose the right products based on patient-specific data.
Key functionalities include a product catalog, a "My Products" feature for saving selections, and the ability to generate a PDF report of the selected items. The app was built with the Ionic framework, Angular, and Capacitor, and leverages Firebase for backend services.

PetComPet Mobile App (Freelance Project)
For this freelance project, I had the opportunity to build a mobile app that connects pet owners. "PetCompet" is a one-stop shop for social networking and shopping, designed to be intuitive and enjoyable for users, with a fun, "Tinder-like" feature that lets users find and connect with other pets in their area.

FlexWorkout - Gym Workout Planner (Side Project)
A mobile hybrid fitness app built with Ionic, Angular, and Firebase (including Google Sign-In). It features: custom workout management, real-time exercise tracking, visual progress charts using ApexCharts, Internationalization (Portuguese and English), and Custom themes (Light and Dark).

Auto Tab Rotator - Chrome Extension (Side Project)
I developed Auto Tab Rotator to solve a common problem: the need to monitor multiple live web pages—like BI dashboards, stock charts, or news feeds—on a single display without manual intervention. This lightweight Chrome extension allows users to create a custom list of URLs and set a time interval, then automatically cycles through them in a single tab. It's a "set it and forget it" solution for creating practical and straightforward information displays.

Dotimer - Time Management & Productivity App (Side Project)
As a personal side project, I developed "Dotimer", a comprehensive time management application aimed at enhancing user productivity. This project was an opportunity to build a full-stack application from the ground up, covering everything from UI/UX design to backend implementation and deployment.","rawText":"PROFESSIONAL EXPERIENCE Full Stack Engineer ACT Digital (ModernaTX) | Remote (USA) | September 2022 – August 2025 - Developed and maintained a pharmaceutical batch tracking system used by hundreds of internal scientists at Moderna - Migrated components from legacy AngularJS to Angular 17 using reactive programming patterns with RxJS and OnPush change detection strategy, following the Single Data Observable Pattern for state management - Built complex forms with extensive pharmaceutical business logic - Refactored AG-Grid business logic, moving to the backend for improved auditability - Integrated data from Microsoft Smartsheet with inconsistent data mappings - Built comprehensive testing coverage using Jest for unit/integration tests and Cypress - Developed backend APIs using Node.js, Express.js, and NestJS with PostgreSQL, writing complex queries with multiple joins. - Collaborated with cross-functional teams in a full English-speaking environment, mentored junior developers through code reviews and pair programming, and worked with product owners to clarify biotech domain requirements in Agile ceremonies. --- Full Stack Engineer Sencon | Passo Fundo, Brazil | February 2020 – December 2021 - Architected and implemented a cryptocurrency and stock portfolio management application serving 135,000+ users, featuring automatic DARF (Brazilian income tax) generation for investors.

Soy un creador digital que convierte ideas en aplicaciones web y móviles reales, funcionales y modernas utilizando herramientas avanzadas, flujos de inteligencia artificial y plataformas. Mi especialidad es transformar conceptos en productos completos: desde la estructura, el diseño, la lógica del negocio, la base de datos y la experiencia de usuario. Construyo soluciones que un desarrollador tradicional tardaría semanas o meses en entregar, pero con una calidad visual sólida y una arquitectura pensada para escalar. He desarrollado sistemas para distintos tipos de proyectos, incluyendo: plataformas deportivas y de torneos, sistemas de reservas y administración, soluciones para restaurantes y cafeterías, apps especializadas para chefs, comunidades gamer y startups que buscan automatizar tareas o lanzar su primer MVP. ¿Cómo puedo ayudarte? Trabajo contigo desde cero: escucho tu idea, la analizo a nivel técnico y funcional, y la convierto en una aplicación clara, intuitiva y fácil de gestionar. Creo prototipos visuales, flujos de usuario, paneles administrativos, bases de datos, automatizaciones y todo lo necesario para que tu proyecto quede listo para funcionar. ¿Qué me diferencia? Uso metodologías impulsadas por IA que permiten construir más rápido, reducir costos, evitar problemas técnicos y enfocarnos en lo que realmente importa: que tu proyecto funcione, se vea profesional y esté listo para crecer. No solo entrego una app, sino un sistema pensado para tu modelo de negocio y tus usuarios. Si tienes una idea o un proyecto en mente, puedo ayudarte a convertirlo en una solución digital real, paso a paso y sin complicaciones. Construyamos algo increíble juntos.","logos":{"normal":{"url":"https://workana.s3.amazonaws.com/logos/2cf230b1a3db6c57db507a8a409fd97f/sl/WhatsAppImage20251023at43851PM_160_160.jpeg","width":160,"height":160},"thumb":{"url":"https://workana.s3.amazonaws.com/logos/2cf230b1a3db6c57db507a8a409fd97f/vv/WhatsAppImage20251023at43851PM_30_30.jpeg","width":30,"height":30},":original":{"url":"https://workana.s3.amazonaws.com/logos/2cf230b1a3db6c57db507a8a409fd97f/ls/WhatsAppImage20251023at43851PM.jpeg","width":580,"height":528},"profile":{"url":"https://workana.s3.amazonaws.com/logos/2cf230b1a3db6c57db507a8a409fd97f/ch/WhatsAppImage20251023at43851PM_192_192.jpeg","width":192,"height":192},"large":{"url":"https://workana.s3.amazonaws.com/logos/2cf230b1a3db6c57db507a8a409fd97f/yy/WhatsAppImage20251023at43851PM_300_300.jpeg","width":300,"height":300}},"country":"US","lastActive":"2025-12-22 22:30:44","created":"2025-05-22 19:38:42","open":0,"active":0,"completed":"0","rating":"0.00","paid":0,"verifiedPaymentMethod":true,"worker":{"id":11326831,"slug":"camilo-rizo","canInvite":false,"skills":{"188":{"id":188},"287":{"id":287},"906":{"id":906},"666":{"id":666},"853":{"id":853},"762":{"id":762},"81":{"id":81},"946":{"id":946},"246":{"id":246},"317":{"id":317},"699":{"id":699},"128":{"id":128},"768":{"id":768},"909":{"id":909},"991":{"id":991},"67":{"id":67}},"history":"Desarrollador de Aplicaciones Web & Móviles (Freelance) 2024 – Actualidad Me especializo en crear aplicaciones web y móviles completas utilizando Base44, Flutter, WordPress y herramientas de inteligencia artificial.

With over a decade of experience in full-stack web development, I now focus on integrating advanced AI technologies transforming applications into intelligent, scalable, and automation-ready systems. I design and deploy AI solutions powered by Large Language Models (LLMs), chatbots, and custom Machine Learning models. My expertise includes LangChain, vector databases (Pinecone, Weaviate, Chroma), and retrieval-augmented generation (RAG) pipelines for enterprise-grade AI assistants. I also build conversational agents, multi-modal interfaces, and real-time analytics tools to enhance user engagement and business productivity. Beyond AI agents, I develop custom APIs, cloud-based AI services, and end-to-end ML pipelines using Python, FastAPI, and Node.js. I integrate third-party AI services (OpenAI, Anthropic, Cohere, Hugging Face) and fine-tune models for domain-specific tasks such as content automation, customer support, and recommendation systems. Proficient with AWS, Docker, and CI/CD pipelines, I ensure seamless deployments, monitoring, and long-term maintainability. My workflow follows Agile practices, automated testing, and continuous optimization—delivering AI systems that are fast, reliable, and built to scale.","logos":{"normal":{"url":"https://workana.s3.amazonaws.com/logos/0ebeacfb3fbc470e1df2266f2729e881/eb/photo_20250824_152901_160_160.jpg","width":160,"height":160},"thumb":{"url":"https://workana.s3.amazonaws.com/logos/0ebeacfb3fbc470e1df2266f2729e881/ku/photo_20250824_152901_30_30.jpg","width":30,"height":30},":original":{"url":"https://workana.s3.amazonaws.com/logos/0ebeacfb3fbc470e1df2266f2729e881/qj/photo_20250824_152901.jpg","width":640,"height":640},"profile":{"url":"https://workana.s3.amazonaws.com/logos/0ebeacfb3fbc470e1df2266f2729e881/cv/photo_20250824_152901_192_192.jpg","width":192,"height":192},"large":{"url":"https://workana.s3.amazonaws.com/logos/0ebeacfb3fbc470e1df2266f2729e881/di/photo_20250824_152901_300_300.jpg","width":300,"height":300}},"country":"SG","lastActive":"2025-12-23 10:22:28","created":"2025-06-04 23:15:52","open":0,"active":0,"completed":"0","rating":"5.00","paid":0,"verifiedPaymentMethod":false,"worker":{"id":10405378,"slug":"lin-jing-an","canInvite":false,"skills":{"947":{"id":947},"1051":{"id":1051},"287":{"id":287},"999":{"id":999},"1012":{"id":1012},"246":{"id":246},"768":{"id":768},"853":{"id":853},"1015":{"id":1015},"280":{"id":280},"748":{"id":748},"991":{"id":991},"711":{"id":711},"1119":{"id":1119},"188":{"id":188},"173":{"id":173},"699":{"id":699},"362":{"id":362},"274":{"id":274},"757":{"id":757},"308":{"id":308},"81":{"id":81},"934":{"id":934},"834":{"id":834},"1013":{"id":1013},"1103":{"id":1103},"990":{"id":990},"749":{"id":749},"67":{"id":67},"525":{"id":525}},"history":"Full Stack Web & AI Engineer – CMI May 2023 – Jun 2024 Designed and built cloud-based insurance dashboards with React, Angular, and Node.js.
